Research firm Telegeography recently reported that Skype users used around 102.5 billion call minutes in the past year, which basically means that around one in five international calls was made over Skype during this time.

Skype suffered from a whole 24-hours of downtime late December 2010 – something of a PR disaster for the company.

However, the VoIP giant now seems to have smoothed over those problems, with the recent iOS and Qik announcements certainly helping to improve its image amongst users.
